WATCH: Trump Just Made A Comment Proving He Failed Politics 101 In College (VIDEO)

President Donald Trump had an interview with Chief White House Correspondent Hallie Jackson just ahead of his first meeting with Russian President Vladimir Putin, and a number of things went seriously wrong.

Before we get into all the specifics, Trump said one thing, in particular, that’s getting the attention of everybody. We aren’t even talking about partisan politics here, or Russia interference, etc. No, that’s not what stands out the most.

What’s more important is Trump being able to answer simple things like, where is the White House located? Or who was the first President of the United States? You know, basic stuff.

So, here’s what happened: when answering one of Hallie’s questions about whether he thought Russia was involved in hacking the 2016 presidential election, he stated he didn’t even know how many intelligence agencies the United States has. He actually said this. Here’s part of his statement:

“I heard it was 17 agencies, do we even have that many intelligence agencies? Right, let’s check. We did some heavy research, it turned out to be three or four. It wasn’t 17.”

For the record, the U.S. intelligence community includes 17 separate agencies and they all issued a joint statement via the Department of Homeland Security and Office of the Director of National Intelligence on Oct. 7, 2016, saying that the U.S. intelligence community was confident that hacks into the email systems of the Democratic Party and its officials were directed by “Russia’s senior most officials.”

Our point is a simple one, if you’re going to be President of the United States, you need to know how many intelligence agencies there are.

Watch the interview here:

The other thing Trump said that’s alarming, but consistent up to this point, is the fact that he still doubts Russia hacked the U.S.

“I think it was Russia. And I think it could have been other people and other countries. It could have been a lot of people interfered.”

Yet – there is no evidence other countries were involved in the cyber attacks. The intelligence community has said this already. So, once again, Trump is attacking the intelligence community.

Critics of President Trump have been questioning his mental capacity for some time now, and this latest comment is only causing more pause for concern, his Twitter antics being a side point.

Whether Trump is suffering from a mental disease or not, we can’t say for sure. With that said, a video of Trump circulated on the internet recently showing him looking extremely confused while trying to find a limo that was waiting directly in front of him. Instead of getting into the limo he walked right past it. A Secret Service agent had to turn him around and point him in the right direction.

While it would be unfair to point to one incident and claim “mental illness,” this seems to be a recurring issue with Trump. Plus, he is the oldest serving president in U.S. history at the age of 70.

People on the inside say “he keeps getting worse, – and mentally, keeps getting worse.” Carl Bernie, a legendary Watergate journalist, told CNN’s Brian Stelter that “We have many reporters, myself included, who have talked to numerous people, Republicans on Capitol Hill, who in private will tell you they doubt the stability of this president.”

If Trump does have dementia or some other issue, he wouldn’t be the first, either. Ronald Reagan was claimed to have Alzheimer’s while still serving his term.

In any case, President Trump can’t even answer basic facts about government. That’s a serious problem.
